Saturn Aura Green Line
The Saturn Aura Green Line starts at $22,695 including destination charge

General Motors has officially announced pricing for its 2007 Saturn Aura Green Line hybrid sedan. The vehicle will retail for $22,695 including destination charge and will also be eligible for a $1,300 tax credit from the federal government for 2007 tax returns.

For comparison, the Honda Civic Hybrid, Nissan Altima Hybrid, Toyota Prius and Toyota Camry Hybrid are priced from $22,985, $25,015, $22,975 and $26,820 respectively, including destination charge.

The 2007 Aura Green Line is considered to be a "mild hybrid" since it cannot move forward under electric power alone. The Aura Green Line hybrid powertrain (164HP 2.4 liter 4-cylinder plus electric motor/generator) is capable of providing mild electric assistance under acceleration, stopping the engine when the vehicle comes to a stop and starting it back up again when the gas is pressed. The car also takes advantage of regenerative braking to help recharge the battery pack.

The Aura Green Line boasts EPA ratings of 28MPG/35MPG city/highway compared to 20/30 for an Aura with the 224HP 3.5 liter V6 and 20/28 for the Aura with the 252HP 3.6 liter V6.

A more viable comparison may be with the Pontiac G6 base sedan. This vehicle is the Saturn Aura's platform-mate and also uses the 2.4 liter 4-cylinder engine and transmission without the hybrid add-ons. EPA ratings for the G6 are 23/33 city/highway which means that the Aura Green Line’s hybrid system affords the driver an additional 5MPG in the city and 2MPG on the highway.

Diesel gives out more energy/volume, so a direct comparison between the two based on MPG to talk about efficiency is misleading at best. Now if you did miles/kJ or a simple %efficiency you'd get somewhere. Also diesel doesn't cost the same as gasoline.

Honestly, I don't get this "Turbo Diesel is better than Hybrid" stuff. It's not like either technology is exclusive. Can I imagine a Turbocharged Biodiesel Hybrid? Would actually be very easy to do, since Toyota's hybrid system (currently the most advanced out of all carmakers), as far as I know, has nothing that would limit to gas powered cars only. The only thing keeping that from happening at the moment is that most hybrid makers (Toyota/Honda/etc.) don't make diesel cars. Least I've never heard of them.

In the short term, both gasoline and diesel will come from petroleum. Both come from the same basic stock-crude oil. And it's not like you can turn crude oil into pure gasoline or diesel. What comes out is simply what was in the crude oil to begin with. In other words-if we all started running on diesel we'd not be able to make enough of it and we'd have a huge surplus of gasoline.

Unless of course you go to biofuels, but that's long term.

Just in case I didn't explain the Crude oil thing well enough...here's an easy place to learn.

Toyota has the D4D naming for its new diesel engines.
The D4D has reached some 2.4l/100km in a closed circuit around Ireland, if I remember correctly (small engine on a small car).
